## AI overview

A ReactOS contributor reports progress on NTFS write support during GSoC Week 6, including cluster assignment through the $BITMAP file and overwriting resident files. The article also describes fixing an 8-byte alignment bug and investigating an undocumented number in file records.

## Source excerpt

This week was rewarding, because I got some things done that I've been wanting to do for a while. Assigning ClustersI wrote some code which can assign clusters by updating the $BITMAP file. As I mentioned last week, this is half of the equation for extending the allocation size of a non-resident file. I'm still working on the other half, which involves storing the assigned clusters in data runs.
